To turn my driver's chair around on my 360, I take the right front and the two rear bolts off after setting up. Then, I twist the rear of the chair towards the center of the mh a couple of inches. Then I release the rotation lever, push the seat back forward, and rotate the chair all the way around.
When we get ready to de-camp, I turn the chair back around, align the holes, and put the nuts and bolts back in.
We did away with the euro chair, just always in the way.
